Données sur le projet

This proposal aims to understand biogeographical patterns and the processes responsible of the origin, adaptation and diversification of the Southern Ocean (SO) biota, particularly of two chironomid midges. We will study the role of historical climatic changes and life-history traits in the distribution of genetic lineages across a latitudinal gradient. We will amplify specific mtDNA and nucDNA markers, identify and characterize genomic and transcriptomic novelties associated to the adaptation of the biota in different areas and will conduct studies of ecophysiological performance and tolerance in the selected taxa including major environmental variables such as temperature. We aim to better understand about the processes involved in the origin, diversification and resilience of the SO biota in space and time.

Méthodes d'échantillonnage

To determine the presence of Parochlus steinenii through the areas described, intensive field surveys were conducted through accessible ice-free areas. At each surveyed location, all accessible rivers, streams, lagoons and lakes were searched in detail over a period of 3-6 h, depending on the weather conditions and local logistics. Presence/absence was determined by examining the shoreline habitats to confirm the presence of larvae, pupae or adults under stones, rocks, sediment and/or submerged vegetation. Water body typology and macrohabitat were described following Hans & Reinhardt (2006). Each site visited was georeferenced using a Garmin 78SC GPS. Climatic variables (water temperature, air temperature, wind speed and relative humidity) were measured and, finally, samples collected of living individuals for research into phenology and physiology, and of individuals immediately preserved in alcohol (95%) for genetic studies. All samples were transported to the Wankara Laboratory at Magallanes University in Puerto Williams, Chile. Characteristics of the species according to the taxonomic key of Wirth & Gressitt (1967) were verified in the laboratory. The species was recorded in all locations surveyed except Diego Ramirez Island and the north-west coast of the Antarctic Peninsula. Survey data were combined with information from a careful bibliographic review (see Torres 1956; Wirth and Gressitt 1967; Brundin 1970; Edwars and Usher 1985; Rauschert 1985; Shimada et al. 1991; Richard et al. 1994; Convey and Block 1996; Allegrucci et al. 2006; Hahn and Reinhardt 2006; Toro et al. 2006; Agius et al. 2008; Rico and Quesada 2013).

Description des étapes de la méthode:

1. The study was conducted throughout the latitudinal and environmental gradient that includes the southern tip of South America in the sub-Antarctic Magellanic ecoregion (54-57°S), and the Scotia Arc distribution of P. steinenii in the sub-Antarctic (South Georgia, 53-54°S) and Maritime Antarctic (South Shetland Islands, 63-64°S) regions. The geographical range of the study involves both small-scale microhabitat environmental gradients and the larger spatial scale 10-degree latitudinal gradient. In the maritime Antarctic South Shetland Islands, we specifically surveyed ice-free areas on Deception, Livingston, Greenwich, Robert, Nelson, and King George Islands. In the north-west coast of Antarctic Peninsula we surveyed the Trinity Peninsula and Litchfield Island. In the CHBR, we surveyed altitudinal gradients located along the north coast of Navarino Island, in Horn Island and the Diego Ramirez archipelago. Parochlus steinenii was found throughout the study area excepting the Diego Ramírez archipelago and the two locations along the north-west coast of the Antarctic Peninsula. Note that, more widely, the species has never been recorded in extensive terrestrial/freshwater studies from any location along the Antarctic Peninsula or from the South Orkney Islands (Chown & Convey, 2016). Fieldwork in the Antarctic was conducted during six austral summer seasons (2013/14 – 2018/19) during field expeditions organized by the Chilean Antarctic Institute (INACH) to the South Shetland Islands and the British Antarctic Survey to South Georgia. In the Magellanic sub-Antarctic region of southern Chile (in the CHBR), fieldwork was organized by the Sub-Antarctic Biocultural Conservation Program of the Universidad de Magallanes. To characterize the distribution of P. steinenii in the South Shetland Islands, we conducted intensive surveys throughout accessible ice-free areas. All accessible sites were sampled for a period of 4-6 h, depending on climatic conditions and logistic support. We additionally sourced all available information from the existing literature (see Wirth & Gressitt, 1967; Brundin, 1970; Allegrucci et al., 2006; Hann & Reinhard, 2006; Toro et al., 2006; Rico & Quesada, 2013). We assessed the presence/absence of P. steinenii (as larvae, pupae or adults) by searching close to the shoreline of lakes and streams, and specifically under rocks and vegetation, and in sediments.
